Vehicle with unique special equipment stolen ex factory! What regulates the insurance??

Moin from a friend was stolen his BMW E46 with absolute full equipment and thus unique special equipment on the front door. The car was a 2002 320d, 4cylinders with full equipment are absolutely rare. From MPaket, over Xenon, large 16:9 Navi and automatic – really all special equipment… Normally the prices for these cars are not so high anymore, but with this equipment from factory already he would have to get more regulated by the insurance or? Ni Does the insurance cover each individual special equipment in its report?
